I am getting an object reference error when trying to display my report. I get this error only after I upgrading to the latest version Q3 2011 (5.3.11.1116).  

With no code changes at all I can down grade to version Q2 2011 SP1 (5.1.11.928) and the report works just fine.

Here is the stack I receive in the Output window while debugging...

Hi,

I'm currently using a report viewer to show different report. The list of report that can be show is in a comboBox. When I clicked on the button "preview", the reportViewer will show the selected item in the comboBox. I notice that if I click many times on the button preview when the report selected is the same, a error appears. Don't know if it is something wrong I'm doing or what, but here is the error that I received :

Server Error in '/' Application

Anyone know what it mean ?

Having trouble figuring this out. What I want is fairly simple, I have a report where all of the data is in metric units. I need to give the user the ability to switch to SI units as sometimes they need to export the data in metric, and other times they need to export the data in SI units.

Hello,

I'm trying to load my first chart using Telerik Reporting. I have this issue:

I want to create a line chart with two series. the data retrieved from sqldatasource is this:

Euribor1Mes    1Y    2.1153391880
Euribor1Mes    2Y    1.5951715250
Euribor1Mes    3Y    1.7828868410
Euribor1Mes    4Y    2.0519780200
...
Euribor1Mes    47Y    3.2136528810
Euribor 1Mes    48Y    3.2181399930
Euribor1Mes    49Y    3.2224216550
Euribor1Mes    50Y    3.2269428250
Libor1Mes    1Y    2.1153391880
Libor1Mes    2Y    1.5951715250
Libor1Mes    3Y    1.7828868410
Libor1Mes    4Y    2.0519780200
...
Libor1Mes    47Y    3.2136528810
Libor1Mes    48Y    3.2181399930
Libor1Mes    49Y    3.2224216550
Libor1Mes    50Y    3.2269428250

The first field is the name of each serie (there are two different), the second field is the X axis data and the third one is the Y axis data.

Can I load two chart series using this data?

Thank you very much.

Hi Telerik Team,

    Is it possible to pass login session (credentials/values) from an asp page to a table datasource in telerik report? if yes, then how do I do it?
    I am using Q1 version. I followed some samples/examples to connect datasource programatically from telerik website but that doesn't produce the results. It causes error message " ExecuteReader: Commandtext property is not initialized for table 1".
    I have login session information in  .aspx page containing reportviewer and one .cs report which is attached to reportviewer.
Would you please reply to dhara.savani@Xerox.com?

Thanks,
Dhara

Hi,

I'm creating my first report, to display an "offer", this offer has an id that I receive as a parameter of my data source.

I created an EntityDataSource, connected it to my data.

I've also added a parameter on the datasource to have only the row with the id in parameter.

Now, I'm a little lost, I've created some textBox, but if I go in the expression editor, in "Fields" I've a "No Data Source", why?

How can I bind the data of my selected row??

Image of my situation

Hello All,

the report columns I want are not specific so that I am generating them dynamically.
I have a query how to bind image column dynamically, i am trying to bind similar to text-box object. but images not shown.

Please provide way to add image column dynamically.

Thank you in advance.

I have a few issues with using charts (a stacked bar chart in this case) and telerik reporting.  Note that we have the Q3 2011 version of the telerik reporting tools.


The first issue is getting the chart to use the correct "labels" for the x-axis.
I have some data which is similar to the following:

Store    Department    Category   PercentA    PercentB
APN        A                    Start            2                    3
APN        A                    End             5                    6
APN        B                    Start            3                    5
APN        B                    End             6                    9
HWT       B                    Start            4                    8
HWT       B                    End             4                    7
HWT       C                    Start            2                    3
HWT       C                    End             8                    8

I then use this data to generate a stacked bar chart.  I use the Category department as the series, so each bar would be split into two (my actual chart has more than 2 categories, but that works fine).  It would then plot PercentA and PercentB on the Y-axes - again no problems.

What I want to do is to use the Store + Department as the x-axis groups.  I am able to use the Store + Department as a group for the tabular display of data, but not on the chart.  The chart currently only creates 1 bar for each Store.  Is there a way for me to tell the chart to use Store + Department for each bar? 


For the second thing, the labels on the x-axis (store) is intersecting the x-axis itself - please see attached screenshot for what I meant.  Is there a way to tell the chart to keep all x-axis labels under the x-axis line?

I have a XAML drawing brush.  I want it to show in the PictureBox on a report.  But the report only takes an image from System.Drawing and not System.Windows.Media.  Any ideas anyone?

// Grab the XAML DrawingBrush

DrawingBrush db = (DrawingBrush)App.Current.Resources["BugIcon"];
// Create an image (wrong kind of Image though)
Image i = new Image()
{
   Source = new DrawingImage(db.Drawing),
   Height = 300,
   Width = 300
};
 
// Need to convert Image to System.Drawing.Image.
RenderTargetBitmap renderBmp = new RenderTargetBitmap(300, 300, 96, 96, PixelFormats.Pbgra32);
renderBmp.Render(i);
 
PngBitmapEncoder encoder = new PngBitmapEncoder();
encoder.Frames.Add(BitmapFrame.Create(renderBmp));
 
using (MemoryStream stream = new MemoryStream())
{
   encoder.Save(stream);
   System.Drawing.Image i2 = System.Drawing.Image.FromStream(stream);
 
   // This is the Telerik report, and the pb1/pb2 are PictureBox controls
   ((Telerik.Reporting.PictureBox)sr.Items["header"].Items["pb1"]).Value = i2;
   ((Telerik.Reporting.PictureBox)sr.Items["header"].Items["pb2"]).Value = i2;
}

Hey All,


I`ve got a report with predefined groupings, however, I now have to add a new group programmatically. I've figured out how to do it, except that I want to add it at the beginning of the Grouping collection, and when i try Report.Groups.Add(newGroup), it adds it at the end...


Right now i have two levels of grouping.

I want to add a third, but i need this new one to be the topmost grouping level.

How can I do this, if at all possible?

Thanks!
